Saw a car (non gm ) at car show in St. Louis a couple of months ago.The owner wasn't around to ask what car the paint came from.The color according to his show card was Wimbelton White.Any idea as to what make model ect.? Would like this on my 67 coupe

Stone

That would be a Ford color. It was used for many years. Pretty common color back in the 60's all the way up to the 80's I believe.
